I'm approaching Lexington on my way to the Corvega factory to wipe out some Raiders. In the nearby countryside, I get a framerate in the mid-30's, down from 60 in general. But looking right at Lexington, it's less than 10.
I have tried about fiddy gazillion tweaks, mods don't matter, with, without.
I've had previous playthroughs without such a horrible frame drop in this area.
Does anyone have any advice?
(If it matters, it's night in-game.)
